Gas enters with liquid resin and stays in product zone, causes molding product part resin content relatively low, product surface
Hickie is shown as, the quality and service life of wind electricity blade are influenced.Therefore, it is necessary to remove gas in resin before priming by vacuum,
To ensure the quality of vacuum infusion molding product.
Currently used is that the liquefied mixture of resin and curing agent is placed into vacuum tank to be kept for certain time so that
Gas removal in liquefied mixture.With the method deaeration efficiency of vacuum tank removing resin and curing agent liquefied mixture bubble compared with
It is low, the rate of flooding demand of megawatt grade blade cannot be met, when form needs frequently to close after injected rubber hose waits for deaeration
Resin equally influences pouring quality, loses more than gain;In addition deaeration again after resin is mixed with curing agent, increases operating time, meeting
Cause liquid resin gel, viscosity rapidly to increase and finally cure, is no longer available for vacuum infusion molding.
As the improvement to vacuum tank defoaming method, in denomination of invention:It is " a kind of for composite vacuum perfusion molding
Liquid resin defoaming method and device ", the patent No.:201010595145.2 Chinese invention patent in, disclose a kind of vacuum
The continuous defoaming method of pouring and forming process liquid resin, mixes liquid resin, and make mixed liquid resin into
Enter the defoaming device of a built-in multi-layer helical laminar flow plate, defoaming device is lasting vacuum state, mixed liquid resin
Continue to flow through from the multi-layer helical laminar flow plate in defoaming device, so that liquid resinous surface area is increased, even if liquid resin liquid level
Becoming a minimum thin layer of thickness, the pressure difference in defoaming device amplifies the bubble volume moment being mixed into liquid resin, and
By lasting vacuum rapidly by these removal of bubbles, the liquid resin handled by deaeration is direct by liquid resin runner channel
It is connected to composite material priming by vacuum scene, molding is irrigated in vacuum state to composite product, realizes liquid resin

But above-mentioned patent has the following defects:First, it is still generally resin and curing agent to liquid resinous mixing
The two-component liquefied mixture being mixed to form, this two-component liquefied mixture need to keep low temperature in the deaeration process, otherwise liquid
State mixture has gel, cured risk, and the general two-component resin for adding curing agent is placed about in about 25 DEG C of room temperature
40min starts the gel that generates heat, and can not use, this makes the time that resin is in liquid shorter, i.e., deaeration in filling process
Operable time it is shorter;Secondly as resin compound flows through multi-layer helical laminar flow plate by its own gravity, resin is mixed under low temperature
It is larger to close object viscosity, is unable to fully disperse so that thickness of liquid film is thicker, and the bubble tension in the resin liquid film of dispersion is larger, nothing
Method fully removes, and influences deaeration effect;Again, deaeration after being mixed with curing agent because of resin, therefore the pipeline of input and output material and deaeration
Device is needing to clean every time after use, otherwise resin and meeting block system after curing agent mixture solidification so that equipment can not
Normal use, and cleaning system needs the resin with one-component, not only wastes raw material, but also be a very cumbersome work
